Risedronate belongs to which class of drugs used to treat osteoporosis?

Explanation:
Risedronate is a bisphosphonate, a class of drugs that slows osteoporosis by inhibiting bone resorption carried out by osteoclasts. It does this by binding to bone mineral and interfering with osteoclast activity, leading to reduced bone turnover and, over time, higher bone mineral density and fewer fractures. Other drug classes work differently: selective estrogen receptor modulators act on estrogen receptors to help preserve bone; calcitonin directly inhibits osteoclasts but is generally less potent; parathyroid hormone analogs stimulate bone formation rather than simply slowing loss. Hence, risedronate is best categorized as a bisphosphonate.
